A Review of Monitoring Techniques for Service Based Applications

A Service-Based Application (SBA) is composed of a number of loosely coupled services available on the network which provide the desired functionalities. Service Based Applications execute in dynamic business environments and have to address evolving requirements. Hence they should be flexible to identify violations and adapt to changes in business requirements or context. Monitoring is the key element for adaptation. A Service Based Application can be viewed in terms of three layers i.e., Business Process Management Layer, Service Composition Layer and Service Infrastructure Layer. Application performance depends on the combined performance of components and their interactions within the SBA layers. Therefore it necessitates to constantly monitor the health of the application by monitoring activities occurring in SBA layers. In this paper we present a view of the monitoring approaches across the three layers.
